I have just released a new update of Hebruby, the Ruby hebrew date conversion library. It is now available as a proper Ruby gem, and has much improved documentation. If your Rails application needs to convert from julian date to a hebrew date, or from a hebrew date to a julian date, or display a date in hebrew (either in hebrew or transliterated into english) this gem is for you.
To install it, just:
gem install hebruby
Thank you to everyone who has helped with Hebruby, especially Joshua Harvey, and enjoy!
